What it does

Plan it first,
knit it happy.

Pick any color

Use yarn you own, or choose any color from the palette, the color wheel or a photo, so you can try a skein you have not bought yet.

Start from a photo

Show it a sweater you like and it fills in the shape, colors, stripes and ribbing for you to check and adjust.

Sweater details

Choose straight, wavy or cable raglan seams with optional contrast piping, patch or kangaroo pockets, and a cable or lace panel down the front.

Copy a motif from the chart

Crop the chart in your pattern PDF, zoom in to count the squares, and see the motif on the sweater. Needs the pattern as a PDF.

Colors you can trust

Yarn colors read from photos pick the yarn, not the label or your hand. If one is off, save the right color to the yarn.

Quick to reach

Open it from the Scan menu to see your sweater patterns, or from a pattern or yarn.

Good to know

The preview is a stand-in that shows where colors go. It is not an exact picture of your pattern. It works with sweater and other garment patterns.
